For me, Call of Duty, Killzone, and Gears are linear shooters (non open world or sandbox shooters). Small routes that lead to the same destination. But enough breathing room for many characters n NPCs to battle throughout the entire game. True corridors (like The Order) are much tighter, as u mainly control Gallahad. They’re all linear shooters, but also different in scope, by each game’s required design.

I think they have to add coop the game is basically made for it, you almost always have someone with you and they often split up,.
I’m not sure about the combat but they should offer a challenge not just one hit kills,.
If they add side quest they would have to open the world up a bit but they could have you looking for upgrade parts.
They should add customizable weapons ie electric thermite rifle where the cloud is must e

Most FPS are corridor shooters (Killzone, Resistance, Call of Duty,, etc). Some are sandbox shooters (Far Cry, Battlefield, etc)

I was trying to think of 3rd Person Shooters that are essentially corridor shooters and Gears is what came to mind. I don’t mean it as an insult. Gears had much grander scale, set pieces, the co-op, tons of things that made it awesome.

The Order 1886 is very narrow scale corridor shooter compared to Gears, but they are both corridor shooters.

If you see the gameplay for Uncharted 4 from I think PAX or Gamescon 2014, I think The Order sequel should go more that route than doubling down on set pieces and linear encounter designs (i.e. corridor shooter). The earlier Uncharted games were mostly corridor / set piece shooting gameplay than the kind of open encounter design I personally find more engaging.

I have no interest in until dawn. I’m not a fan of adventure style games in general and until dawn does a lot of hand holding with all those icons everywhere showing you what to touch. No mystery there.

For what you describe, you should play Quantic Dream games (stand out being Heavy Rain). The upcoming Until Dawn on PS4 will also be going with similar philosophy of no game over screen (i.e. story continues even if you fail, even if your character dies).

There are others as well. The Life is Strange Episodic game with Episode 1 out has similar, except they let you rewind time on your most recent choice so you can change the outcome.

Thanks to u, I now realize that Gears is a “corridor shooter”.
